基于驾驶员路径选择的动态交通仿真模型

Route-based Dynamic Traffic Simulation Model

描述一个基于路径的动态交通仿真模型 (RDTS) ,它使用一个微观交通流仿真器结合一个驾驶员路径策划器来实现路网中每辆车从出发地到目的地行程的模拟。应用开发的时间相关最短路模型 ,驾驶员在向目的地前进途中可以根据交通条件的动态变化而动态地选择和变更路径。RDTS模型采用一个路径选择模型来模拟详细的动态交通分配过程 ,并且致力于反映路网中个别车辆的行为表现及其相互作用 ,其中包含车辆生成、路径选择和车辆移动模型 ,可以很好地应用于驾驶员动态路径诱导领域。

This paper presents a route?based dynamic traffic simulation (RDTS) model, a microscopic traffic flow simulator with a route planner to help implement drivers′ desire to travel the least cost routes from the origins to destinations Using a developed time?dependent shortest path model, drivers can dynamically choose and change routes towards their desired destinations according to dynamic traffic conditions The RDTS model incorporates a route choice model to simulate detailed dynamic assignment process, and aims to reflect the detailed performance of individual vehicles and their interactions in a roadway network This RDTS model also explores dynamic traffic phenomenon (e g queuing) at intersections under signal control or at uncontrolled intersections The RDTS modeling procedure encompasses traffic modeling techniques that address the issues related to vehicle generation at a centroid, vehicle route choice, and vehicle movements The RDTS model is applicable to different types of large?scale networks, such as an urban traffic control network or a freeway network to obtain dynamic traffic patterns The simulation structure allows the system operation to adequately reflect time?varying guidance, which drivers receive as they travel through the network
